Has anyone on here built their 7 with rear-exiting exhausts (if that's the term)? Maybe a bit less fumes-in-the-face and might look kinda funky? Have seen the toniq with side ported exhaust and internal can, was thinking similar but piped to the rear of the car.

I was thinking heat maybe a problem? Maybe reduced power from a longer exhaust? Also the fuel tank would be right there by the can...

What you think folks?

Has been done before. My first seven, a VM, had a rear exit. A friend of mine build one on his Westfield after he got tired of the noise and fumes. Works a treat. You can route the exhaust throught the tunnel but I've never seen this. Mine had a normal side damper and the exhaust then was routed close to the diff and into another damper under the fueltank. Perfect in regards to noise and fumes, bit heavy though.

Like this,bigrich has done it to his zx10r mac1,looks great

that does look pretty funky.

anyone driven the toniq? or anything else with that kind of side ported exhaust? do the fumes get to you or is it no worse than a regular side pipe exhaust?

Sweeeeet!

I seem to remember that Tiger racing had a Tiger R6 with an exhaust across the rear panel.
I was taken for a ride in it and it just left all the noise behind.
Hope someone can confirm.

this is my mac#1 with rear panel in place
Yes kipper the tiger that was at brands kitcar live had a rear silencer across the back, i followed it for a few laps whilst it dumped fuel out over the silencer

My Tiger Super Six has a rear exit exhaust - mounted as normal along the side then runs through the front of the rear wheel arch, and up and over the axle in a big bend, emerging just under the the back of the arch. I like it, it loses some of the noise (silencer has NO packing in it I think - hellishly loud), it looks cool and for trackdays I've got a carbon R1 can that mounts sideways behind the spare tyre and gets attached with a 90deg bend tube and some exhaust clamps. Not pretty, but cheap and works ok.

I'd say to go for it!
